Tonight's Sky for January 12: Be Alert for Aurora

NOAA is advising people in
upper latitudes to be alert for aurora tonight as t he Earth is now
in the midst of a co-rotating interaction region (CIR), which is a
fancy way of saying that the Earth is transitioning from a fast to
slow moving solar wind stream. There were expectations that Earth
would enter this region today but aurora were reported last night,
meaning that the chances are rather good that the show will continue
tonight as well.
